I found this when investigated "Bug 32319 - .gdb_index is broken/incomplete" for LLD. When we have object file with .debug_ranges section it may be filled with zeroes. Relocations are exist in file to relocate this zeroes into real values later, but until that a pair of zeroes is treated as terminator. And DWARF parser thinks there is no ranges at all when I am trying to collect address ranges for building .gdb_index. Solution implemented in this patch is to take relocations in account when parsing ranges.
